摘　　要：对聚丙烯酸酯(PA)、聚氨酯(PU)、聚氯乙烯(PVC)3种不同的涂层篷盖布进行热老化处理,探讨其耐热性能的变化。研究表明:a)随着温度的升高、时间的延长,3种涂层织物的强力均有不同程度的下降,强力下降程度依次为:PVC涂层,PU涂层,PA涂层;b)在175℃条件下,随着时间的延长,3种织物的质量均越来越轻,其中,PA、PU两种涂层篷盖织物的质量变化不太明显,PVC涂层篷盖织物的质量损失较为明显;c)PA、PU涂层篷盖布的耐热性优于PVC涂层篷盖布;d)热处理后,PA、PU涂层织物表面变得相对光滑平整,PVC涂层织物表面出现微小孔洞,涂层颗粒明显。The purpose of this paper is to study the heat-resistant quality of fabrics coated by PA,PU and PVC.The study shows ：（1） With the increase of temperature and time,the strength of three kinds of coated fabric decline with different degree.Order of them： PVC,PU,PA;（2） With the extention of heated time,the quality of three kinds of coated fabric becomes lighter.The quality change of PA and PU is small,but the quality change of PVC is big;（3） The heat resistance of PA and PU is better than PVC.（4） After heating treatment,PA and PU coating fabric surface becomes relatively smooth;Small holes of PVC coated fabric surface appear and coating particles are obvious.
